How was I abusive? I was simply pointing out that it's very hard to read a post like that.

Perhaps my wording was a little harsh, but I meant no offence.

Just ordering the materials for this job - couple of questions please, gents.

For a top coat 6:1:1 sand: cement: lime - should the lime be Hydrated lime, not hydraulic lime?

Sand - supplier says 'sharp sand' for rendering - I thought there was a 'rendering' type of sand which is coarser than building sand but not 'sharp'? The supplier has 'plastering sand' - is this probably the same as 'rendering sand'?

Is it definitely worthwhile using some lime in the top coat for extra flexibility, even if I'm using 4:1 sand:cement (no lime) for the first coat?

Sorry for all the questions, I want to get this right!

This is rendering onto 7N dense concrete blockwork.

Thanks!

hydrated lime if used with cement,buy from somewere that moves a few pallets its dead if its been on the shelf for a month!
sand,yes sharp but just as important washed.
limes well worth it m8,why not stick it in the scratch if not waterproofing,your arms will love ya

As the man says , lime will make it nice gear to uses ifnot adding w/p in the scratch
